Warnings and Cautions
WARNING
R410-A Refrigerant under Higher Pressure than R-22!
The units described in this manual use R410-A refrigerant which operates at 50 to 70% higher
pressures than R-22. Use only R-410A approved service equipment. Refrigerant cylinders are
painted with "pink" color to indicate the type of refrigerant and may contain a "dip" tube to allow
for charging of liquid refrigerant into the system. For specic handling concerns with R-410A,
please contact your local sales ofce.
Failure to use R-410A approved service equipment could result in standard equipment exploding
under R-410A higher pressure which could result in death or serious injury.
NOTICE
Use appropriate oil with R410A systems. Oil type is found at the bottom of Connection Pipe
Requirements table (included in the outdoor unit installation manual). R-410A systems utilize POE
(Polyolester) or PVE(Polyvinyl Ether) oil. Both oil types absorb moisture readily, yet, lubrication
properties vary. Do not leave the sealed system open to atmosphere except during service for a
short period of time. If the sealed system is left open longer than four hours, the compressor oil
must be changed. These systems utilize strainers placed before and after the expansion device in
the outdoor unit, if debris or moisture is suspected, these strainers must be changed. Do not break
a vacuum with air. Do not leak check the sealed system with compressed air. Unless instructed by
factory service representative, external refrigeration driers are prohibited.
USE ONLY THE FACTORY RECOMMENDED OIL TYPE!
Important!
Environmental Concerns
Scientic research has shown that certain man-made chemicals can aect the earth's naturally occurring stratospheric ozone layer
when released to the atmosphere. In particular, several of the identied chemicals that may aect the ozone layer are refrigerants
that contain chlorouorocarbons (CFC's) and those containing hydro-chlorouorocarbons (HCFC's). Not all refrigerants containing
these compounds have the same potential impact to the environment. The Company advocates the responsible handling of all
refrigerants, including industry replacements for CFC's such as HCFC's and HFC's.
Responsible Refrigerant Practices
The manufacturer believes that responsible refrigerant practices are important to the environment, our customers, and the air
conditioning industry. All technicians who handle refrigerants must be certied. The Federal Clean Air Act (Section 608) sets forth
the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these
service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for
responsible management of refrigerants. Know the applicable laws and follow them.

1. Installation should performed by a qualied HVAC professional. Industry Standard Personal
Protective Equipment (PPE) and gear for height related safety should be worn during installation.
Improper personal safety precautions and installation may cause death or serious injury.
2. Install the air conditioner according to the instructions given in this manual. Incomplete installation
work may cause water leakage, electrical shock or re.
3. Use the supplied or specied installation parts. Use of other parts may cause the unit to come loose,
resulting in water leakage, electrical shock or re.
4. Install the unit in a location that can support the weight of the unit. An inadequate support structure
or incomplete installation may cause injury or property damage in the event the unit falls o of the
installation location. Refer to the installation specications for additional requirements.
5. Electrical work should be carried out in accordance with the installation manual and local, state and
National Electric Code (NEC). Insucient capacity or incomplete electrical work may cause electrical
shock or re.
6. Use a dedicated power circuit. Never use a power supply shared by another appliance.
7. For wiring, use a cable that is long enough to cover the entire distance without splicing. Do not use an
extension cord. Do not put other loads on the power supply; use a dedicated power circuit. Failure to
do so may cause abnormal heat, electric shock or re.
8. Use the specied types of wires for electrical connections between the indoor and outdoor units.
Firmly clamp the interconnecting wires so their terminals receive no external stresses. Incomplete
connections or clamping may cause terminal overheating or re.
9. After joining the interconnecting and supply wiring, shape the cables so that they do not put undue
force on the electrical covers or panels. Install covers over the wires. Incomplete cover installation
may cause terminal overheating, electrical shock, or re.
10. If any refrigerant leaks out during the installation, ventilate the room. The refrigerant produces a toxic
gas if exposed to ames.
11. When installing or relocating the system, keep the refrigerant circuit free from substances other than
the specied refrigerant (R410-A), such as air. The presence of air or other foreign substances in the
refrigerant circuit can cause an abnormal pressure rise or rupture, which could result in injury and
damage.

Pre-Installation Checklist
1. Unpack and inspect each unit.
2. Check for any damage to the unit.
3. Check the model numbers to ensure a proper match.
4. Check the unit nameplate to ensure the proper electrical requirements will be met.
5. Check the installation locations to ensure the weight of the units can be supported.
6. Check the refrigerant pipe sizes and ensure they have been or will be installed according to the requirements in
this manual.
7. Check the outdoor unit nameplate for electrical power supply and wiring requirements to ensure the proper wiring
has been installed prior to connection.
8. Check the indoor unit for coil leakage. The pressure relief valve on the gas pipe should release pressurized
nitrogen which ensures the unit has not leaked during shipping.
CAUTION
1. Do not install the unit in a place where there is danger of exposure to ammable gas leakage. If gas
leaks and builds up around the unit, it may result in re.
2. After system installation is completed, make sure no refrigerant leakage is present.
3. This appliance is not intended for use by persons with a lack of experience and knowledge, unless
they have been given adequate supervision or instruction concerning use of the appliance by a
person responsible for their safety.
4. Children should be supervised to ensure that they do not play with the appliance.
NOTICE
1. Establish drain piping according to the instructions in this manual. Inadequate piping may cause
ooding.
2. Tighten the are nut according to the specied method. If the are nut is tightened too hard, the are
nut may crack and cause refrigerant leakage.
12. If a system pump-down is performed, turn o the associated equipment and close service valves prior
to removing the refrigerant piping. Failure to do so will introduce non-condensables in the system,
causing abnormal pressure in the refrigeration cycle which could lead to injury and damage.
13. Before system start-up, attach the refrigerant piping securely. Failure to do so will introduce non-
condensables into the system when the compressor is running, causing abnormal pressure in the
refrigeration cycle which could lead to injury and damage.
14. Establish a complete ground. Do not ground the unit to a utility pipe, arrester, or telephone ground.
An incomplete ground may cause electrical shock, or re. A high surge current from lightning or other
sources may cause damage to the air conditioner.
15. If the power supply cable is damaged, it must be replaced by the manufacturer, its service agent or
another qualied professional in order to avoid electrical risk during and after replacement.
